74 - 8 x W = 22
Solve for W
Answer:W=6.5
Step-by-step explanation:
74-8w=22
subtract 74 from both sides
-8w=-52
divide both sides by -8
w=6.5
Answer:
-8w=22-74
-8w=52
w=52÷(-8)
w=-6.5

Let us first solve the triangle on the right side involving angle x.
Recall that the sum of angles in a triangle must be equal to 180°.
So we can write
[tex]\begin{gathered} 41+78+x=180 \\ 119+x=180 \\ x=180-119 \\ x=61\degree \end{gathered}[/tex]Therefore, the angle x is equal to 61°
Now let us solve the triangle involving angle S and T.
Again applying the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} 48+57+S=180 \\ 105+S=180 \\ S=180-105 \\ S=75\degree \end{gathered}[/tex]As you can see, the angle S and T form a straight line angle.
Recall that a straight line angle is equal to 180°
[tex]\begin{gathered} S+T=180 \\ 75+T=180 \\ T=180-75 \\ T=105\degree \end{gathered}[/tex]Therefore, angle S = 75° and angle T = 105°
Now let us solve the remaining figure.
On the right side of the figure, apply the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} A+42+40=180 \\ A+82=180 \\ A=180-82 \\ A=98\degree \end{gathered}[/tex]As you can see, the angles A and B are opposite angles.
We know that opposite angles are equal.
[tex]\angle A=\angle B=98\degree[/tex]Now we know the angle B so let us apply the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} B+48+C=180 \\ 98+48+C=180 \\ 146+C=180 \\ C=180-146 \\ C=34\degree \end{gathered}[/tex]Therefore, angle A = 98° and angle B = 98° and angle C = 34°
45^2 ÷ 78 = ????????
To solve the problem find the value of (45)^2 at first
[tex](45)^2=2025[/tex][tex]\frac{2025}{78}=25\text{ R75}[/tex]The answer is 25 with the remainder 75

A battery is charged. The percentage of the battery's capacity that is charged as a function of time (in minutes) is graphed 50+ 70 50+ Capacity charge 20+ 10 What was the battery's charging level when the charging began? 12
The equation of the line (segment) is:
[tex]y=2x+40[/tex]Where y is the percentage of the charge, and x is the time (in minutes) that has passed since the charge started.
How do we know that? Because we can identify two points in the graph shown in the image:
[tex](0,40),(5,50)[/tex]
Notice that the line intersects the y-axis in point 40 (when the battery had 40% of its charge)
You can easily see that the equation I first wrote is correct by simply substituting the values of those two points I just wrote above.
Since we need 'the battery's charging level when the charging began', we need to set x=0, as we need the value of y (percentage of the charge) when the charging started.
So, if x=, then:
[tex]y=2\cdot0+40=40[/tex]Therefore, the answer is 40%

find the average rate of change of f(x)=x^2 on the interval [1,5]
The function supplied has an average rate of change for the range (1, 5) of -6.
f(x) = 17 - x2 (assumed)
The average f(x) change rate for the time period has to be determined (1, 5)
The function f(x) spanning the range (a, b) changes at an average rate equal to
A and b are valued as 1 and 5, respectively, in this instance.
f(1) = 17 - (1)2
f(1) = 17 - 1
f(1) = 16
f(5) = 17 - (5)2
f(5) = 17 - 25
f(5) = -8
It was determined that f's average rate of change (x)
As a result, the function supplied has an average rate of change for the range (1, 5) of -6.

[tex]\frac{6}{3^8}[/tex]12. How many centimeters are there in 740.2millimeters?A 7402 cm© 7.402 cmB 74.02 cmD 0.7402 cm
In this kind of question, we always need to know what is the equivalence between two measures:
We already know that in 1 centimeter there are 10 millimeters. With this equivalence, we can write:
740.2 millimeters * ( 1 centimeter / 10 millimeters )
When we have a unit in the numerator and also in the denominator, like millimeters, in this case, both units are converted in 1, and they do not need to be in the final answer (millimeters/millimeters = 1). Therefore:
740.2 * ( 1 centimeter / 10 ) =
( 740.2 / 10 ) centimeter =
When we divide a number by 10, 100, 1000, we write the decimal point to the left as many zeros have the 10, 100, 1000. In this case, we only have one zero.
Thus, we write the decimal part one digit to the left:
( 740.2 / 10 ) centimeter =
74.02 centimeter (this is the answer).
Therefore, there are 74.02 centimeters in 740.2 millimeters.

in the diagram (triangle) ABC = (triangle) PQR. Reflect (triangle) ABC across the line y = x. Describe how to map image to (triangle) PQR.
First we have to find the line y=x so we can do the reflection:
now in the graph we can se that the lines RO and BC are parallel to the line y = x
and there you can see that they are the same by moving the triangle 5 units to the right.
Other way you can check they are iqual, is by calculate the area of the triangles.

A sum of money is to be shared among three friends Paul, Mark and Anna in the ratio 2: 3: 5 respectively. If Paul received $ 48,000. Determine
a. Anna’s Share
b. Mark’s share.
c. The total sum
a)Sum of money share by Anna is $120000
b)Sum of money share by Mark is $72000
c) The total sum the three friends have is $ 240000
The ratio of the amount of money shared among three friends is 2: 3: 5.
Let's take the common factor to be x.
Sum of money Paul has = 2x
Sum of money Mark has = 3x
Sum of money Anna has = 5x
It is given that Paul receive $48000
So,
2x = 48000
x = 24000
a) Anna's share = 5x
= 5× 24000
= $120000
b) Mark's share = 3x
= 3 × 24000
= $72000
c) The total share = 2x + 3x + 5x
= 10x
= 10 × 24000
= $240000
Therefore the sum of money share by Anna is $120000, Mark is $72000 and the total sum of money is $240000.

The estimate by rounding to the nearest hundred. Then solve.
Jonah picked total 626 cherry tomatoes if she licked 287 cherry tomatoes in May and 330 cherry tomatoes in June.
As the mentioned numbers are in hundreds and not in thousands, the number can not be rounded. Now we will need to perform addition to find the total number of cherry tomatoes picked by Jonah combined in May and June.
Total number of cherry tomatoes = 287 + 339
Performing addition to find the total number of cherry tomatoes picked by Jonah
Total number of cherry tomatoes = 626
